H/5 A TTOENEX Patented July 13, 1948 This invention relates to socalledhead gear gogglsand is concerned primarily with-the mode ofmounting a pair of goggles on a headgear.

v Aheadgear goggles-of the type with which this invention is concernedincludes as essential elements-a headgear and a pair of goggles. Theheadgear is adapted forsnug fitting on the wearers head and is intendedto constitute theanchor'age to which the goggles are attached. While theheadgear is more or lesspermanently worn, that is, it will remain inposition during the worldngtday, the gog les will, vfromtirme to time,bee-swung from a protective position into anout tv the way positionabove the wearer's forehead. In-providinga means for attaching thegoggles to.,the headgear so as to permit of thenecessarymanipulation-,it is desirable that a high degree of. simplicity. beachieved and the, number of partsheld down to anabso-lute minimum. Thisnot. only assures of easy operation as thegogglesare" being,moved ,-,buteliminates any parts which might obstruct the vision.

V Accordingly, this invention has in view asiits foremostobjective, theprovision of a headgear gogglesof-the type aforesaid in whichmeans isprovided foroperatively attaching :the goggles to the headgear centrallyof the goggles.

More in detail the inventionhas as its object theaprovision ofayheadgear goggles: of the type noted in whichthe attaching meansissecured to the bridge ofthe goggles.

In. order to-insure accurate fitting. of the goggles the goggle elementshave been hingedly connected. In accordance with this invention acertain amount of relative pivotal movement between the" individualgoggle elements is permitted by the attachment to the headgear.

Aiurther object of the invention isthe-provision',.in a headgear gogglesof the character described,v of "attaching means comprising a linkhavinga pivotal connection at one end of the headgear and a pivotalconnection at the other endjwith the bridge of the goggles. Associatedwith eachof the pivotal connections is meansfor generating frictionwhich functions to maintain thergoggles in an adjusted position.

Another important feature ofthepresentinvention resides in theparticular meansfor connecting the attaching means to; the gogglesbridge.- In accordance with this invention, the link'is pivotallyjoinedto a bracket-and-there is a pivotal connection between each individualgoggle elementand this -bracket.;- Thus: each goggle element may! hepivoted slightlpwith respect? torthe bracket.=-= Thesrhinged connectionbetween the The 1 men, therefore, comprises a head-- gear os'z',consisting" of aheadg'ear end a-pair or mean onriecte'djgog'g'l demeritswhich are gear. goggles made in accordance with'the precents: of thisinvention;

The latter maybe provided with a sweat-band such as indicated at M, in accordance withcommon practice. It is evident that this frontpart i3 is intended to besnugly fitted over the front part of the wearers head. A rear headgearpart is designated at I5 and as shown is pivotally attached to, thefront part ill by the pivotal connections Hi, there being a pivotalconnection on each side. This rear part i3 is rendered adjustable inlength by adjusting means shown at H.

Adjusting devices of this type are well known in this field and any suchmeans of adjustment which is found satisfactory may be employed. It isevident that by availing of the adjusting device 11, the headgear H inits entirety, may beaccurately fitted on the head of any particularwearer.

Th'e goggles G are shown as comprising the individual goggle elements 48and I9. The actual assembly of each of these elements [8 and i9 is not aparticular part of this invention. Ordinarily each will include an outerprotective glass which is replaceable and the inner ray-filter, whichwill protect the users eyes from excessive light. The outer glassprotects the ray-filter from flying particles of metal or other materialwhich might damage the more expensive rayfilter. These glasses areremovably contained in the circular frames illustrated. The frame of thegoggle element [8 is shown as being provided with a lug carrying hingeears 2|. The frame of the goggle element 89 is provided with a lug 22which carries hinge ears 23 that are complemental and interfitted withthe ears 2|. A hinge pin 24 passes through aligned openings in the ears2| and 23 to establish the hinge connection. It is notable that there isa loose fit between this hinge pin and the ears. This looseness permitsthe adjustment which will later be described.

The connecting attachment C includes a bracket 25 which extends acrossthe top faces of the lugs 23 and 22. At one end the bracket part 25 ispivotally joined to the lug 26 by the pivot screw shown at 26. At theother end the bracket 25 is pivotally joined to the lug 22 by the pivotscrew shown at 21. It is evident that the pivotal connections 26 and 21between the bracket 25 and the lugs 20 and 22 formed on the individualoggle elements, together with the looseness in the hinge joint definedby the hinge pin 24 and openings in the ears 2i and 23, permits acertain amount of angular adjustment between the individual goggleelements 18 and I3.

Included as a part of bracket 25 are a pair of spaced ears 28. Anotherbracket 29 is permanently secured to the headgear H by rivets shown at30 which securely anchor the bracket 29 to the front part I!) of theheadgear. This bracket 29 also carries a pair of spaced ears 3| and thespacing of these ears corresponds to the spacing of the ears 28.

A connecting link L is made up of two complemental halves 32 and 33. Atone end the link L is positioned between the ears 3| and pivot pin 34passing through aligned openings in the ears 3! and halves 32 and 33establishes the pivotal connection. It will be noted that the openingsthrough the link halves 32 and 33 are enlarged as shown at 35 to providea counterbore which receives an expansion spring 36. This expansionspring tends to spread the link halves apart and press them against theinner faces of the ears 3| and thus create a required amount offriction. The other end of the link L is similarly positioned betweenthe ears 28 and the pin 31 and establishes the pivotal connection in themanner above described. A spring 33 will also be located in acounterbore 35 and disposed about the pin 31 to generate friction atthat end of the link.

With the device thus described, it is apparent that suitable provisionis made for angularly adjusting the goggle elements so that they willsnugly fit about the eyes of the wearer. The friction created at thepivots 34 and 31 serves to maintain the goggles either in a protectiveposition in front of the wearers eyes or in an out of the way positionabove the wearers forehead.

The goggles may be moved by grasping them at any convenient part, suchas one of the handles shown at 9, and the central location of theconnection to the headgear renders such manipulation a matter which iseasily carried out. Moreover, the anchorage to the headgear is firm andsecure and will not be impaired by continued use of the device.

Figures 4 and 5 illustrate a modified form of the invention in which theconnection between the headgear H and goggles G is shown as including anadditional pivotal connection. Thus, the pivotal connection at 34 to thebracket 29 on the headgear remains the same as does the connection at 31to the bracket 25 on the goggles G. However, between the pivots 34 and31 the structure is changed from the form shown on Figures 1, 2 and 3. Alink identified as l is secured at one end to the pivot pin 34 in themanner above described, and a second link I1 is connected at one end tothe pivot 31. These links I and I1 are formed of complemental halves asabove described in connection with the link L and are joined togetherintermediate the pivots 34 and 31 by another pivot pin 33. This pivotpin 38 may also be provided with a spring for creating friction as abovedescribed in connection with pivots 34 and W. The purpose of thisadditional pivotal joint in the connection C is to facilitate themanipulation of the goggles G with respect to the headgear H as itprovides a variety as to adjustment and number of positions which areobtainable in excess of that provided by two pivotal joints.

While preferred specific embodiments of the invention are hereinbe'foreset forth, it is to be clearly understood that the invention is not tobe limited to the exact construction illustrated and described becausevarious modifications of the details may be provided in putting theinvention into practice within the purview of the appended claims.
